CLAIM OF PRIORITY

The present application is a continuation of U.S. application Ser. No.13/027,195, filed Feb. 14, 2011, now U.S. Pat. No. 8,784,095, and titledOXYGENATED FUEL, which claims priority to and the benefit of U.S. PatentApplication No. 61/304,403, filed on Feb. 13, 2010 and titled FULLSPECTRUM ENERGY AND RESOURCE INDEPENDENCE, which applications areincorporated herein by reference in their entireties. To the extent theforegoing applications and/or any other materials incorporated herein byreference conflict with the disclosure presented herein, the disclosureherein controls.

BACKGROUND

This application relates to devices, techniques and materials related tobiofuels.

In general, fossil fuels in modern engines provide incomplete combustionand create adverse heat transfers, particularly in automotive engineapplications. In large part, this is because conventional operation ofengines provides for homogeneous-charge combustion and allows quenchingof fuels undergoing combustion with consequent heat losses to thepiston, cylinder walls, and head components along with pollutiveemissions. After quenching of combustion, partially burned fuelconstituents pass out of the combustion chamber to the exhaust system tocause further efficiency losses and pollution of the atmosphere. In bothhomogeneous-charge and diesel engine operations, liquid fuel dropletsmust be evaporated and depolymerized or “cracked” to promote combustion.These processes require heat from the air or from the combustion ofother fuel constituents and considerable time for these events to becompleted in order to complete the combustion process. About ⅓ of theheat released by combustion is lost through the cooling system of theengine and is dissipated to the environment through the radiator.Engines are designed to open the exhaust valve when the hot combustiongases still have considerable pressure and thus substantial amounts ofheat and pressure potential energy is lost through the exhaust system.About ⅓ of the heat released by combustion is lost through the exhaustsystem of the engine and is dissipated to the environment.

In order to provide for marginal relief from atmospheric pollution, fuelpurveyors have promoted more complete combustion of fossil fuels byadditions of supplements such as methyl tertiary butyl ether or “MTBE” acompound with the molecular formula C₅H₁₂O. However because ofgroundwater water contamination by MTBE a more recent practice has beento add ethanol a compound with the formula C₂H₅OH. The concentration ofsuch oxygenated additives has been about 5% to 10% of the total fuelmixture. In practice it has been shown that such additions of oxygen atthe carbon to oxygen ratio of 5:1 or 2:1 for a relatively small fractionof all the fuel molecules present in the combustion process helpspromote more complete combustion by providing oxygen for oxidation ofother fuel constituents. Nevertheless, considerable additional expenseis incurred for catalytic reactors for attempts to marginally reduce airpollution from engines using hydrocarbon fuels with additions ofethanol. Such air pollution remains objectionable particularly incongested cities and can cause or exacerbate lung diseases, heart andcirculatory problems, corrosion of construction materials andcontributes to greenhouse gas accumulation problems.

DETAILED DESCRIPTION

The ignition delay of conventional diesel fuel made of a mixture oflarge-molecules as liquid-fuel constituents includes the time toevaporate and crack these molecules and then penetrate enough additionalhot air to ignite. Small gaseous molecules, such as hydrogen (H₂) andcarbon monoxide (CO) have much less delay and eliminate particulateformation. The time to complete combustion of any fuel is a function ofthe heat required to evaporate and crack the fuel, availability of theoxidant, heat released by combustion, and degree to which the heatrelease is conserved. In order to equalize kinetic energy in apopulation of mixed mass molecules, small molecules have much highervelocities than large molecules. Small molecules like hydrogen travelfaster, traverse greater distances, collide more often, and diffuse morerapidly than larger molecules at the same temperature. Hydrogen burns ina much wider range of air-fuel ratios than most hydrocarbons. This alongwith the higher heat release as hydrogen oxidizes is why hydrogen burns7 to 10 times faster than hydrocarbon fuels.

Techniques, structures, apparatus and materials are disclosed forgenerating oxygenated fuel for use in an engine to increase fuelefficiency by providing the oxygenated fuel before the combustionchamber to achieve a more complete combustion of the fuel. In addition,the process of providing the oxygenated fuel can prevent damages to theengine cause by the incomplete combustion process.

Oxygenation of Carbon-Donor

FIG. 1 is a process flow diagram of an exemplary process 100 forgenerating oxygenated fuel from substances that include hydrogen andcarbon such as biomass waste and industrial waste. A system (e.g.,system 300 below) obtains a carbon donor, such as carbon, hydrocarbon oralcohol from biomass dissociation (110). Copending U.S. patentapplication Ser. No. 13/027,068 filed Feb. 14, 2011, now U.S. Pat. No.8,318,997, and entitled “CARBON-BASED DURABLE GOODS AND RENEWABLE FUELFROM BIOMASS WASTE DISSOCIATION” describes the techniques and systemsfor biomass waste dissociation, the entire contents of which areincorporated by reference. Briefly, Equation 1 below shows an exemplarygeneral process for biomass waste dissociation to produce a carbon suchas the hydrocarbon methane.C_(x)H_(y)O_(z)+HEAT→CH₄+H₂+CO₂+CO  Equation 1

Using the process described in Equation 1, virtually any organicmaterial can be converted in large part to hydrocarbon fuel, such asmethane (CH4) for distribution and storage in the existing natural gasinfrastructure. Equation 2 below illustrates a general summary ofoverall reactions of an embodiment for production of methane fromtypical biomass wastes such as glucose, lignin, and cellulosicfeedstocks.C₆H₁₂O₆+HEAT→3CH₄+3CO₂  Equation 2

In some implementations, the biomass dissociation reaction can producealcohols, such as methanol as a readily storable and transportableliquid fuel and chemical precursor. Methanol or “wood alcohol” can beextracted by heating lignocellulosic wastes through partial combustionor by anaerobic heating processes. Equations 3 and 4 summarize theoutput of methanol that can be achieved by selection of differentanaerobic operating temperatures, pressures, and catalysts.C₆H₁₂O₆+HEAT→6CO+6H₂  Equation 36CO+6H₂→3CH₃OH+3CO  Equation 4

The system also obtains an oxygen donor to oxygenate the carbon donor(120). The system causes the carbon donor to react with the oxygen donorto oxygenate the carbon donor to obtain the desired oxygenated fuel(130). The reaction is endothermic, in which heat used in theoxygenation reaction can be harvested from waste heat of an engineexhaust or cooling system. Also, heat used in the reaction can beobtained from a renewable source of energy, such as wind and solar powergenerators. Moreover, the equipments for the wind and solar powergenerator can be produced using carbon-based materials, which werecreated from the carbon extracted from the biomass dissociation.

The oxygenated fuel can be used in a stratified charge-combustionsystem, such as a diesel or gasoline engine (140) that has beenconverted to such operation. In some implementations, the combustionsystem can include a stratified charge combustion system. The oxygenatedfuel can increase the fuel efficiency by promoting more completecombustion and also prevent engine damages caused by normally incompletecombustion process.

For example, an industrial operation or refining operation can producepressurized carbon dioxide, carbon monoxide and/or hydrogen by partialoxidation of a carbon donor or by reaction of a carbon donor with steamas generally shown in Equations 5-8.2C+1.5O₂→CO+CO₂  Equation 5CH₄+H₂O+HEAT→CO+3H₂  Equation 6C_(x)H_(y)+0.5xO₂ →xCO+0.5yH₂  Equation 7CH₄+0.5O₂→CO+2H₂+HEAT₂  Equation 8

Equation 7 summarizes partial oxidation of a hydrocarbon compound, whichcan be beneficial for producing hydrogen along with oxygenated carbon.Equation 8 summarizes the partial oxidation of methane. The oxygenutilized in the processes of Equations 7 or 8 may be supplied by air,air filtration, air separation processes, or by electrolysis of acompound such as water that separates oxygen from another substance suchas hydrogen.

Extensive studies of the combustion rates at various pressures show thatcarbon monoxide combusts at a much slower rate than hydrogen. Forexample, see Hongyan Sun, S. I. Yang, G. Jomaas, and C. K. Law;High-pressure laminar flame speeds and kinetic modeling of carbonmonoxide/hydrogen combustion, Proceedings of the Combustion Institute 31(2007) 439-446. However, the described techniques and systems providesfor much faster combustion of carbon monoxide or mixtures of carbonmonoxide including other relatively slow burning hydrocarbonconstituents or with much faster burning hydrogen by minimizing orpreventing oxides of nitrogen from forming, for example.

Previous approaches for gaining an advantage by electrolysis of waterusing “off-peak” renewable electricity or grid-delivered electricityfrom mixed power sources or by electrolysis on board a vehicle includingarrangements for regenerative braking to produce electricity and or heatto dissociate a compound such as water have wasted the oxygen or addedoxygen to a fuel cell or an engine. The present invention derives a muchgreater benefit by oxygenation of carbon to produce a fuel or fuelmixture with much more rapid combustion characteristics and results. Animportant benefit of the “oxygenation” of all the carbon in the originalfuel is the assurance that all of the carbon will be rapidly combustedwithout particulate production in the combustion process (e.g.,stratified-charge combustion) that is enabled by Fuel injector ormulti-fuel injector technology.

For the reaction of Equation 9 below, coal wastes, sawdust, refinerywastes, oil tar, grain processing dust, forest-fire debris, particledust from manufacturing processes that utilize carbon compounds aresuitable sources for production of oxygenated carbon.C+H₂O+HEAT→CO+H₂  Equation 9

FIG. 2 is a process flow diagram of an exemplary process 200 forselectively producing oxygenated fuel in a multi-fuel environment. Asystem (e.g., system 300 below) can receive a carbon donor from biomassdissociation (210). The process for biomass dissociation to obtainvarious carbon donors is described above with respect to FIG. 1. Thesystem also receives an oxygen donor in the form of oxygen, steam,water, etc. (220).

The system causes the carbon donor to react with the oxygen donor (e.g.,oxygenation) in an exothermic or endothermic reaction (230). Formulti-fuel applications, depending on the chemical nature of the fuelstored in a tank, the system can include one or more heat exchangersthat selectively apply varying degrees of heat and pressure to producescorresponding varieties of hydrogen-characterized fuels for improvingthe operation of an engine (240). For example, wet methanol can bevaporized and dissociated by addition of heat to produce hydrogen andcarbon monoxide as shown in Equation 10. Equation 11 shows endothermicreforming of inexpensive wet ethanol or with addition of an oxygen donorsuch as water:2CH₃OH+H₂O+HEAT→5H₂+CO+CO₂  Equation 10C₂H₅OH+H₂O+HEAT→H₂+2CO  Equation 11

When compounds such as cellulose and fuel alcohols, which containoxygen, are dissociated by anaerobic decomposition, the general processas illustrated with ethanol feedstock is shown regarding Equation 12.C₂H₅OH+HEAT→C+CO+3H₂  Equation 12

Hydrogen and carbon monoxide of desirable quality to be directlyutilized in most of the world's existing engines is released by thedissociation process generalized by Equations 5-12, for example.Hydrogen characterized fuels produced according to such reactions can beused to fuel an engine or used as a low cost fuel for customers' heatengines including piston and gas turbine types. In such applications, afuel injector or a multi-fuel injector described in U.S. Pat. No.6,756,140 entitled “Energy Conversion System,” the entire contents ofwhich are incorporated by reference, can be used to improve powerproduction, clean the air, and extend engine life while using suchhydrogen-characterized fuel.

The selectively generated oxygenated fuel can be used in a combustionsystem, such as a converted gasoline or diesel engine (250). In someimplementations, the combustion system can include a stratifiedcombustion system.

FIG. 3A is a block diagram showing an exemplary system 300 forgenerating oxygenated fuel from biomass waste. The system 300 includes abiomass dissociation system 310 that receives biomass waste 302 to bedissociated into carbon-donors 322, such as carbon, hydrocarbons,alcohols, ammonia and hydrogen using a thermochemical regenerativeprocess. The heat used to dissociate the biomass waste 302 can includewaste heat from sources such as fuel cell and/or engine exhausts, enginecooling system etc. that otherwise would be released to the environment.Also, one or more of renewable energy sources, such as wind, solar, etc.can be used to generate the heat.

The carbon-donors 322 received from the biomass dissociation system 310are forwarded to an oxygenated-fuel generating reactor 320, whichincludes a heat transfer system for heating or cooling mechanism 324.The oxygenated-fuel generating reactor 320 can also receive additionalor different carbon donors, such as CO₂ 326 harvested from industrialprocesses (e.g., exhaust gases from fossil fuel combustion or air) 304.In addition, the oxygenated-fuel generating reactor 320 receivesoxygen-donors 332 from an oxygen-donor harvesting system 330.

The oxygenated-fuel generating reactor 320 causes the receivedcarbon-donors 322 and 326 to react with the harvested oxygen-donors 332to generate an oxygenated fuel mixture that can include carbon monoxideand hydrogen. The reactor 320 with the heating mechanism 324 performsheat transfers and operations to accomplish thermochemical regenerationfor efficient reaction. The system 300 can also include a controller(not shown) that adaptively adjusts the coordination of pumps (notshown), valves (not shown), and heating operations to optimize specificand overall the processes. Methane can be delivered by a pressureadjusting pump (not shown) from the biomass dissociation system 310 tothe heating mechanism 324 where it is heated to approach thedecomposition temperature by countercurrent heat exchange from hydrogenand/or carbon monoxide exiting the oxygenated fuel generation reactor320.

Hot coolant and the exhaust from an engine can successively supply wasteheat to one or more counter current heat exchangers (e.g., part of theheating mechanism 324) and the reactor 320 in which a precursor such asmethane, naphtha, ethanol, or methanol and/or other products from freshor fossil biomass which may be delivered by a suitable transport systemincluding a pipeline and reacted with an oxygen donor 332, such as waterand/or oxygen to produce hydrogen and carbon monoxide according toEquation 6.

The generated oxygenated-fuel or mixture 328 can be stored at storageand/or transport system 350. Also, the oxygenated-fuel or mixture 328can be sent to a combustion system 360, such as a converted dieselengine. In some implementation, the combustion system can include astratified charge combustion system. The generated oxygenated-fuel ormixture 328 can include small gaseous molecules, such as hydrogen (H₂)and carbon monoxide (CO), which have much less delay and eliminateparticulate formation. As described above, small molecules like hydrogentravel faster, traverse greater distances, collide more often, anddiffuse more rapidly than larger molecules at the same temperature.Hydrogen burns in a much wider range of air-fuel ratios than mosthydrocarbons. This along with the higher heat release as hydrogenoxidizes is why hydrogen burns 7 to 10 times faster than hydrocarbonfuels.

Equation 6 above, which is reproduced below, shows that the amount ofwater produced by combustion of a hydrocarbon, such as methane, is twoor three times as much water as needed to reform methane into moredesirable hydrogen-characterized fuel. Also, Equations 6 (reproduce fromabove) and 13 below show the advantage of reforming a hydrocarbon suchas methane and burning the resultant fuel species (H₂ and CO) ofEquation 6 to produce more expansion gases in the power stroke of thecombustion chamber along with producing more water for reformingreactions in a reactor (e.g., reactor 320).CH₄+H₂O+HEAT→CO+3H₂  Equation 63H₂+CO+2O₂→3H₂O+CO₂  Equation 13

In other words, reforming methane with water to make and combustproducer gas (hydrogen and carbon monoxide) provides more combustionenergy and about three-times as much product water as needed for theendothermic reformation of methane in the reactor (e.g., oxygenated fuelgeneration reactor reactor 320). Thus, along with water condensed in aheating mechanism (e.g., heat exchanger 324) of the reactor ample watercan be collected by a vehicle or stationery application of thetechniques and system for generating oxygenated fuel 328. This is a veryimportant advantage for minimizing curb weight because most of theweight of water used in the oxygenated fuel generating reactor 320 isgained by combustion oxygen from the air with hydrogen orhydrogen-characterized fuel in the engine. Thus, each gram of hydrogencan combine with eight grams of atmospheric oxygen to provide nine gramsof collectable water from the exhaust of engine.

In some implementations, power for propulsion and manufacturingoperations can be provided by one or more heat engines that utilizethermochemical regeneration principles to increase thermal efficiency.For example, heat released by engine combustion can be harvested andrecycled using heat exchangers. In addition, steam generated by burningof the oxygenated fuel can be used in the reaction of Equation 6 tooxygenate the carbon donors 326 and 322. Thus, both waste heat and waterbyproduct (e.g., steam) of an engine or reactor that combust theoxygenated-fuel 328 can be recycled to enhance an anaerobic (e.g.,thermochemical or electroysis of water) reaction.

The system 300 can also include a filtration/precipitation system 340 tofilter the carbon-donors, such as methane or other hydrocarbons and fuelconstituents to remove sulfurous substances such as odorant, sulfides,and metal organics. When the presence of an odorant is desired, theappropriate odorant can be added, after the filtration, fromconcentrated sources that meter the desired amount into thecarbon-donors. For example, semiconductor detectors of fluid leakage canbe implemented at far lower concentrations than can often be detected bysmelling an odorant.

FIG. 3B is a block diagram showing an exemplary system 310 fordissociating biomass waste into hydrogen and carbon carryingintermediaries. The system 310 includes a biomass waste intakecomponent, such as a hopper 311 that receives the biomass waste 302 inraw form and breaks down (e.g., chips, chops, grinds, etc.) the rawmaterial into subdivided feedstock, such as various cellulosic andlignocellulosic materials. The hopper 311 can include a heatingmechanism, such as a heat exchanger 312 to pre-heat the subdividedfeedstock. The heat exchanger can recapture and recycle waste heat froman external heat source (e.g., engine exhaust and/or renewable heat,such as wind, solar, etc.) or from biomass dissociation reactor 314itself.

The subdivided (and in some implementations, pre-heated) feedstock 313is forwarded to a biomass dissociation reactor 314 to dissociate thebiomass waste feedstock into useful renewable sources of carbon andhydrogen, such as various hydrocarbons, alcohols, ammonia, and oxides ofcarbon. The reactor can include a drying mechanism 315 to expel moistureand air from the feedstock. The drying mechanism 315 can include anextruding device to physically ‘squeeze out’ the moisture and air fromthe feedstock. Examples of the extruding device include a helical screwconveyer and a ram piston conveyer. Also, the drying mechanism 315 caninclude one or more heating mechanisms, such as heat exchangers thatcapture heat generated by the reactor 314 and recycle the captured heatto dry the feedstock. The heat exchangers can also recapture and recyclewaste heat from an external heat source (e.g., engine exhaust and/orrenewable heat, such as wind, solar, etc.)

The reactor 314 can also include a heating mechanism 316 for generatingadequate heat used in an anaerobic reaction to dissociate the biomasswaste feedstock into the useful renewable sources of carbon and hydrogen317, such as hydrocarbons, alcohols, ammonia and oxides of carbon. Thegenerated useful renewable sources of carbon and hydrogen 317 can beforwarded to a storage and/or transport mechanism 318 to be used by theoxygenated fuel generation reactor 320 and in additional reactions togenerate renewable fuel and/or carbon-based durable goods 319 asdescribed in the copending U.S. patent application Ser. No. 13/027,068filed Feb. 14, 2011, now U.S. Pat. No. 8,318,997, entitled “Carbon-BasedDurable Goods and Renewable Fuel from Biomass Waste Dissociation,” theentire contents of which is incorporated by reference. Moreover, thestorage and/or transport mechanism 318 allows for efficient transport ofthe useful renewable sources of carbon and hydrogen 317 to remotelocations for further processing.

The biomass dissociation reactor 314 can be configured to increase thethermal efficiency of the biomass waste conversion process whilereducing or eliminating carbon dioxide formation. For example, thebiomass dissociation reactor 314 can include mechanisms to performvarious countercurrent drying (e.g., recycling heat) and elimination ofair, moisture, and other oxygen donors prior to extraction of carbon,hydrocarbons such as methane, and/or hydrogen.

The described techniques and system allow utilization of biomassalcohols from much lower-cost production methods by allowing substantialwater to remain mixed with the alcohol as it is produced by destructivedistillation, synthesis of carbon monoxide and hydrogen and/or byfermentation and distillation. This enables more favorable energyeconomics as less energy and capital equipment is required to producewet alcohol than dry alcohol. Further it facilitates the utilization ofwaste heat from an engine to endothermically create hydrogen and carbonmonoxide fuel derivatives and to release up to 25% more combustionenergy than the feedstock of dry alcohol. Additional benefits arederived from the faster and cleaner burning characteristics provided byhydrogen. By utilization of Fuel injector or multi-fuel injector tometer and ignite such hydrogen-characterized derivative fuel as astratified charge in unthrottled air, overall fuel efficiencyimprovements of more than 40% compared to homogeneous charge combustionof dry alcohol(s) are achieved.

Thermochemically Shifted Carbon Monoxide

In another aspect, when substantial sources of carbon dioxide areavailable such as from the stack gases of fossil fueled power plants,such carbon dioxide can be harvested, separated, and purified asdisclosed in the U.S. Pat. No. 6,984,305, the entire contents of whichare incorporated by reference. FIG. 4 is a process flow diagram showingan exemplary process 400 for generating thermochemically shifted carbonmonoxide for use as oxygenated fuel. A system (e.g., system 500)harvests CO₂ from industrial processes as described above (410). Thesystem also harvests a carbon-donor (e.g., from biomass dissociation)(420). The industrial process harvested CO₂ can be repurposed andrecycled as a source of thermochemically shifted CO by reacting thefossil produced carbon dioxide with a renewable carbon donor (e.g., frombiomass dissociation) as shown in Equation 14.CO₂+C→CO  Equation 14

Ultimately, such CO₂ and carbon wastes are heated sufficiently in ananaerobic environment to release desirable gases, carbon, and solidresidues such as mineral oxides and other compounds (430). The heat usedin the reaction to generate the thermochemically shifted carbon monoxidecan be obtained from waste heat of an engine exhaust or cooling system(440). Also, heat or energy from renewable resources, such as wind orsolar energy generators can be used. As described with respect to FIG. 1above, even the equipments for the renewable energy generation can beproduced using carbon extracted from biomass dissociation.

The thermochemically shifted CO can be used as oxygenated fuel mixturein an engine (e.g., a combustion system), such as a stratified chargeengine (450).

FIG. 5 is a block diagram of an exemplary system 500 for generatingrenewable fuel from thermochemically shifted CO reacted with hydrogenfrom biomass waste dissociation. The system 500 includes a biomassdissociation system 310 that receives biomass waste 302 to bedissociated into carbon, hydrocarbons, alcohols, ammonia and hydrogenusing a thermochemical regenerative process. The heat used to dissociatethe biomass waste 302 can include waste heat from engine exhausts,engine cooling system etc. that otherwise would be released to theenvironment. Also, one or more of renewable energy sources, such aswind, solar, etc. can be used to generate the heat.

From the biomass dissociation system 310, carbon donor 322 (fromdissociation of hydrocarbons, for example) is captured and forwarded toa carbon monoxide (CO) generating reactor 510, which includes a heatingmechanism 512. The carbon donor 322 is reacted with CO₂ 522 harvestedfrom industrial processes (e.g., exhaust gases from fossil fuelcombustion or air) 520. The CO generating reactor 510 can cause thecarbon donor 322 to react with the harvested CO₂ 522 to generatethermochemically shifted CO 514.

The thermochemically shifted CO 514 is forwarded to an engine 520 andused as oxygenated fuel. Also, the thermochemically shifted CO 514 isstorable and transportable at a storage container 530.

In some implementations, an electrolyzer can be included to supplyoxygen to pressurize or be added to pressurized constituents in a heatexchanger to oxidize a portion of a quantity of feedstock and or providepartially oxidize such fuel constituents and supplement the heatavailable by heat exchanges from sources such as solar, engine jacketheat, and exhaust heat. Moreover, the heat from reactions within theoxygenated fuel generating reactor 320 or thermochemically shifted COgenerating reactor 510 can be recycled as part of the heat used forendothermic processes and or exothermic reactions described above.

Separation of CO and H2 and Storage

Hydrogen produced by the reaction of Equations 8-10 may be separatedfrom carbon monoxide by a suitable separation system such as diffusionthrough a membrane in a separator (not shown) or by pressure swingadsorption or temperature swing adsorption is stored in an accumulator30 which may be of the type disclosed in U.S. Pat. Nos. 6,446,597 and6,503,584, the entire contents of which are incorporated by reference.Carbon monoxide can be stored in another accumulator and may be used asfuel in an engine 520 or as a fuel source to fuel injector and sparkigniter to provide supplemental heat for accelerating thermochemicalregeneration in the reactors 320 and 510. Such separation facilitatesthe utilization of relatively pure hydrogen independent of CO.

Tangible and Useful Applications: Fuel Injector or Multi-fuel Injectorfor Efficient Engine Operation

The described techniques for generating oxygenated fuel (e.g., CO orCO+H₂) can be applied to an engine that implements a Fuel injector ormulti-fuel injector that may be similar to the integrated fuel injectionand spark ignition devices disclosed in U.S. Pat. Nos. 3,830,204;4,066,046; 5,343,699; 6,155,212; 6,446,597; 6,756,140; or 7,628,137, theentire contents of these patents are incorporated by reference. Inaddition, multi-fuel injector technology can be implemented to provide aprocess of multi-fuel presentation for ignition and combustion that mayinclude carbon monoxide, mixtures of carbon monoxide and other fuelconstituents, or carbon monoxide and non-fuel substances or in thealternative may include other fuel selections such as diesel fuel,gasoline, propane, fuel alcohols, wet fuel alcohols, wet fuel alcoholswith carbon donor additions, or hydrogen provides for much more rapidcompletion of combustion processes than possible by previous approaches.Multiple layers of oxidant and fuel can be provided in the combustionzone of a fuel combustion system. Positive ignition of multiple directfuel injections to form pancaked layers of fuel separated by air oranother suitable oxidant such as oxygen in different zones can providemuch more rapid completion of combustion processes. Multi-fuel injectioncan be controlled using a controller that provides a drive signal for apiezolectric or electromagnetic or hydraulic or pneumatic valveoperation to deliver fuel to the combustion chamber of the engine.

The controller may subsequently provide a drive signal to ignite one ormore layers of fuel as they enter the combustion chamber, during thetime fuel is entering the combustion chamber or after fuel has enteredthe combustion chamber. Such ignition may be by a spark or by bursts ofmore than one sparks or by continuous application of spark plasma andmay be applied with or without catalytic fuel modification within asystem or with or without catalytic ignition at the location of fuelentry into the combustion chamber. The controller may receiveinformation about the pressure and or the temperature resulting from thefuel introduction and or ignition and or combustion events in thecombustion chamber by wireless communication or by instrumentation lead.The controller can control the pressure of fuel delivery through aconduit to the combustion chamber and may also receive flow rateinformation by wireless communication and or by the lead or a similarmethod of communication.

In addition, adaptive control may be provided for the timing andduration of each fuel injection, and the timing and duration of eachignition, and of the fuel delivery pressure by the controller to produceconstant rpm, a desired acceleration or deceleration, maximum fueleconomy, or minimum oxides of nitrogen, or certain operatingtemperature(s) of one or more engine components such as pistons, valves,a cylinder wall, or the rings of the pistons.

Consequently, higher torque can be developed per calorie or BTU (BritishThermal Unit) for greater fuel efficiency and to prevent oxides ofnitrogen from being formed. Higher torque per BTU is provided by timingthe ignition of more rapid combustion processes closer to, at, or aftertop dead center (TDC). Thus the resulting higher surface to volume ratioprovides for much more rapid heating of air between and around thepancaked layers of combusting fuel than possible with previoustechnologies.

Oxides of nitrogen are greatly reduced or prevented by igniting locallyfuel-rich mixtures that propagate combustion into locally air-richmixtures to limit peak combustion temperatures of such zones to 2200° C.(4000° F.). Additional benefits are provided by the more rapidcompletion of multiple stratified charge combustion for preventingformation of oxides of nitrogen by reducing the time for oxides ofnitrogen to be formed and reducing or eliminating quench preservation ofany oxides of nitrogen that may be formed.

Another important benefit is that hydrogen may be co-produced byregenerative braking or application of off peak electricity along withsubsequent oxygenation of carbon. Hydrogen combusts 7-10 times fasterthan fossil fuels such as methane, octane, propane, ethane and dieselfuel constituents. In applications on engines operating at relativelyhigh frequency such as 3,000 to 15,000 rpm (revolutions per minute) verylittle time is available for completion of combustion and hydrogen maybe used at times that an expedited combustion process is needed.Multiple stratified coniform fuel charges or flatter stacks of “fuelpancakes” with air or air-rich or oxygen or oxygen rich layers betweensuch multiple stratified coniform fuel charges or flatter stacks of fuelpancakes expedites the completion of combustion of all fuel selectionsbut operation of high speed engines with hydrogen is particularlybeneficial. At relatively low piston speeds, slower burning fuels suchas methane, ethane, propane, octane, gasoline, or fuel alcohols may bedelivered through a conduit. At higher piston speeds, faster burningfuels may be added to supplement or replace such slower burning fuels.Illustratively, hydrogen or mixtures of hydrogen and carbon monoxide maybe delivered by a conduit for adding to or replacing slower burning fuelselections.

The power, as may be measured as horse power “HP” developed by an engineis equal to the product of brake mean effective pressure “BMEP” or “P”,the length of stroke of the piston for providing torque, and thefrequency or number of cycles of operation per unit of time “N”HP=PLAN  Equation 15

As summarized in Equation 15, more power can produced because P isincreased and more rapid completion of combustion enables N to also beincreased for additional power or more torque by gear-reduction whenneeded. In addition, more heat can be delivered to the combustionchamber by the faster burning oxygenated carbon and hydrogen than theoriginal fuel would release upon combustion.

Computer-aided controls and components provide direct-injection andspark-ignition of traditional and alternative fuels in internalcombustion engines can provide important improvements toenergy-conversion efficiency with hydrocarbon fuels and enablesutilization of lower cost renewable fuels including hydrogen, methane,and oxygenated carbon regardless of octane or cetane rating. Fuel ormulti-fuel injection can provide full rated power production withgaseous fuels such as natural gas, renewable methane, or hydrogen thatrequire far greater fuel flow rates to provide the same heating value asDiesel fuel. Adaptive electronic controls monitor crankshaftacceleration, cylinder pressure, and piston speed for purposes ofminimizing fuel use through all duty cycles including start-up, idlecontrol, acceleration, transient operation, cruise, frequency matching,and full-power development. Each fuel injection and ignition event ismonitored and adjusted to produce maximum torque within the selectedduty cycle. The variables are timing of fuel injection, spark ignition,and amount of fuel injected.

Tangible and Useful Applications: Thermochemical Regeneration

Thermo chemical regeneration and/or regenerative braking energy can beutilized or combined in a Thermochemical Regeneration process to producegreater fuel values from hydrocarbon fuels and an oxygen donor such asmethanol and or water. Heat recovered from the cooling and exhaustssystems and/or regenerative braking produce hydrogen from hydrocarbonfuels or water and convert hydrocarbons and a suitable oxygen donor byendothermic steps including vaporization and formation of gaseous fuelspecies that yield greater energy upon combustion than the originalhydrocarbon precursor fuel.

Tangible and Useful Applications: Efficient Improvements for EmissionsReduction

As described above, the ignition delay of conventional diesel fuel madeof a mixture of large-molecules as liquid-fuel constituents includes thetime to evaporate and crack these molecules and then penetrate enoughadditional hot air to ignite. Small gaseous molecules (such as H₂ andCO) have much less delay and eliminate particulate formation. The timeto complete combustion of any fuel is a function of the heat release,availability of the oxidant, and degree to which the heat released isconserved. In order to equalize kinetic energy in a population of mixedmass molecules, small molecules have much higher velocities than largemolecules. Small molecules like hydrogen travel faster, traverse greaterdistances, collide more often, and diffuse more rapidly than largermolecules at the same temperature. Hydrogen burns in a much wider rangeof air-fuel ratios than most hydrocarbons. This along with the higherheat release as hydrogen oxidizes is why hydrogen burns 7 to 10 timesfaster than hydrocarbon fuels.

Increased BMEP for improving specific power rating: One way to improveBMEP is to prepare fuel constituents that burn more rapidly to enablepressure development during the power stroke for reduced backwork duringthe compression stroke. Reversible theoretical cycle efficiency is notinfluenced by pressure, however practical cycle efficiency is greatlyinfluenced by pressure because the greater the pressure the faster thecombustion process and backwork and heat losses are reduced duringcompression in nonadiabatic positive-displacement engines.

Reaction rates for CxHy are generally much slower than for smaller H₂and CO molecules in which the surface to volume ratio of the smallmolecules are larger than for larger hydrocarbons. The first step ofreacting carbon in a hydrocarbon is an endothermic reaction in whichheat is required to release the hydrogen from the carbon in order forthe carbon to be oxidized. Subsequently, the greater portion of heatreleased by hydrocarbon-sourced carbon combustion is from the step ofcarbon monoxide being oxidized to form carbon dioxide a shown inEquations 16-17:C+0.5O₂→CO−47,517 BTUs/Mole  Equation 16CO+0.5O₂→CO₂−121,666 BTUs/Mole  Equation 17

The described techniques can provide heat transfer from the coolingfluid and exhaust system for endothermic reactions to prepare freehydrogen and fully oxygenated carbon as carbon monoxide. This canprovide improved system efficiency, reduces maintenance and extendsengine life because less heat is transferred from these fast burningfuels to the piston, rings, cylinder walls and valve assemblies.

In addition to hydrogen produced by regenerative braking, engine coolingjacket temperature is adequate to provide significant heat addition forendothermic thermochemical regeneration process steps. Exhaust gastemperatures are substantially adequate to add heat at highertemperatures to accomplish completion of endothermic reactions withhydrocarbon feed stocks including liquid and lower-cost gaseous fuelssuch as landfill methane as shown in above described Equations 6, 13(reproduced below) and Equation 18:CH₄+H₂O+HEAT₈→CO+3H₂  Equation 6CO+3H₂+2O₂→CO₂+3H₂O+HEAT₉  Equation 13CH₄+2O₂→CO₂+2H₂O+HEAT₁₀  Equation 18

The heat of reaction at constant pressure of Equation 18 is −344,940BTU/Mole. In the combustion process shown in Equation 13, −103,968BTU/Mole for 3 moles of Hydrogen=−311,904 BTU; and −121,666 BTU/Mole forcombusting CO provide a total yield of −433,570 BTU. This is the lowerheating value without any credit for the heat of condensation of 3 molesof water. Compared to Equation 18, Equation 13 yields −88,630 BTU moreenergy than burning the methane directly. Thus, about 25% morecombustion energy is delivered for production of work. Thermochemicalregeneration does not require the new fuel species to be used atelevated temperature and the new species can regeneratively transferheat to the thermochemical process. The Heat₈ used to reform methane andwater into oxygenated carbon and hydrogen may include heat transferredfrom the engine's cooling system and heat transferred from the engine'sexhaust system and may further include heat contributed by partialoxidation of a carbon donor fuel.

Tangible and Useful Applications: Dissociation of H2-Dense Fuel Used asSolvent to Isolate Contaminants

In some implementations, methanol and water solution produced from areaction of biomass dissociation produced hydrogen with CO₂ harvestedand repurposed from industrial processes may also serve as a solvent forsoluble organics that are functional hydrogen and carbon donors. Forexample, a thermochemical regeneration may utilize waste heat from arenewable energy source, fuel cell or heat engine and the inexpensive“wet” liquid mixture or may contain soluble carbon or various organicsthat are depicted as “C” as shown in Equation 19.CH₃OH+H₂O+C+HEAT→2CO+3H₂  Equation 19

The heat of reaction of methane at constant pressure of Equation 18 is−344,940 BTU/Mole. But for three moles of hydrogen it is 3(−103,968BTU/Mole)=−311,904 BTU; and 2(−121,666 BTU/Mole)=−243,332 for combusting2CO in Equation 19 for a total yield of −555,236 BTU. This is the lowerheating value without any credit for the heat of condensation of 3 molesof water. Compared to Equation 18 (yielding −344,940), it yields−210,296 BTU more energy than burning the initial feedstock methanedirectly. Thus, about 60% more combustion energy is delivered forproduction of work by the engine. Thermochemical regeneration does notrequire the new fuel species to be used at elevated temperature and thenew species can regeneratively transfer heat to the thermochemicalprocess.

Suitable soluble carbon donors include food-processing wastes, paperprocessing wastes, grain dust, molasses residues, bagasse, and variousresidues of the fossil fuel industry including coal dust, refinery coke,and tar wastes.

Thus depending upon the loading of soluble organics in the wet methanol,25% to 60% more heat is delivered to the combustion chamber and can beutilized more efficiently by fuel injectors or multi-fuel injectors asmulti stacks of stratified combustants to combust more rapidly andeliminate particulates and oxides of nitrogen by adaptively controlledtiming of the initial fuel injection and ignition, timing of eachsubsequent fuel injection and ignition and the fuel pressure of eachfuel injection.
